ABSTRACT:
Thin walled sleeves of heat recoverable material are made by inserting the opposing edges of a length of heat recoverable material into a thermoplastic insert having incorporated therein a peroxide or other heat activatable crosslinking agent, placing a reinforcement comprising a foraminous member, for example, a strip of glass cloth, or other high melting material, of relatively open weave adjacent to the insert and in contact therewith, followed by heating the assembly to form a weld. Optionally, a combination of the foraminous member and film can be placed in contact with the insert.
